Seven American runners will find out tomorrow if they have won back Olympic relay medals stripped from them because of doping by team‑mate Marion Jones.

The Court of Arbitration for Sport said today that it is ready to issue its ruling on the appeal against the athletes' disqualification from the 2000 Sydney Olympics.

The International Olympic Committee nullified the results and took back the medals in 2007 after Jones admitted using performance-enhancing drugs.

In Sydney, Jones won gold in the 4x400 relay. The squad also included Jearl Miles-Clark, Monique Hennagan, LaTasha Colander Clark and Andrea Anderson.

Chryste Gaines, Torri Edwards, Nanceen Perry and Passion Richardson won bronze medals along with Jones in the 4x100 relay. All but Perry appealed to CAS.

The seven believe they should escape punishment for cheating by Jones, who was also stripped by the IOC of gold medals in the 100m and 200m and bronze in the long jump.

At a two-day hearing in May, lawyers for the relay runners said the sport's rule book in 2000 prevented teams from being disqualified for one person's doping.

A CAS ruling five years ago said team‑mates of Jerome Young should not lose their 4x400 gold medals after he was given a retroactive ban from 1999-2001 – meaning he was technically ineligible for the games.

However, Young did not run in the 4x400 final at Sydney, while Jones was part of both quartets that clinched the medals.
